Abstract
A method of threading a weft insertion jet nozzle so that a correct length of the leading end of the weft thread extends from the jet nozzle in the direction of the shed includes the steps of bringing a weft thread into its corresponding jet nozzle, inserting at least one weft length of said weft thread into the shed, cutting off the length of weft thread which has been inserted into the shed so that the correct length of weft thread extends from the outlet of the jet nozzle, and finally removing the cut-off length of weft thread from the shed. A weaving machine adapted for carrying out the described method includes a control unit connected to the weaving machine's prewinders, jet nozzles, a suction nozzle, a cutter, and to the drive of the sley of the weaving machine.
